Wet underfloor heating controllers (feddit.uk)

Just wondered if anyone on here is using a HA compatible one.
Zigbee or Z-Wave would be fine.
Unfortunately, the controllers I got with the main control unit are Heatmiser.
They use Zigbee, but the manufacturer's own implementation which requires buying and running a proprietary hub (and sod that!)
Rather annoyingly, the controllers are pretty functional!
The manifold wiring centre itself (UH4) just works by connecting 240v lines, so shouldn't be too hard to have HA connecting the right loops at the right time.

I've considered just doing this with shelly relays and setting up a thermostat in HA, so if anyone has homebrewed an interesting solution, I'd also be interested to hear!

I'm using Z-TRM3 by Heatit for a part of our floor heating. The controlling itself works just fine, but I've seen a bit of interference on z-wave network after installing that and also there's an annoying feature that you can't manually control the heater if you turn it off from z-wave (I want that my devices can function as dumb ones if needed). So, not an answer to your question, but based on that one single unit I wouldn't recommend that, even if it's decently priced and looks pretty good on paper.

That's indeed useful information!
My boiler control for the central heating has the very useful function of a 30 minute button.
Which means even if I torpedoed HA in the middle of winter, I could still get the house warm.
